Emma Wilson, 25, was sentenced to life in jail with a minimum of 14 years for the murder of her 11-month-old son Callum.
Speaking following the sentencing, Det Supt Ian Hunter said:
The sentence today is a reflection of the abuse Callum suffered at the hands of someone entrusted to care for him and the pain he must have felt during his short life.
It also reflects on the dedication and efforts of the investigating officers and prosecution team to deliver justice for Callum during what was a difficult and emotional case for many of them.
Of course, sadly it does not bring Callum back and our thoughts will always remain with him.
